DOOR-HOOK.

Specification of Letters Patent.

Patented Jan. 14, 1919.

Application filed February 6, 1918. Serial No. 215,713.

To all whom it may concern:

Be it known that I, JOHN MCCORMICK, a citizen of the United States, and resident of Northville, in the county of Spink and State of South Dakota, have invented a certain new and useful Door-Hook, of which the following is a specification.

The object of my invention is to provide a hook to be secured to screen doors or other closure members and so constructed and arranged that when not in use it will be auto matically folded over to position close to the door whereas when in use it may be swung to position extending away from the door.

l/Vith this and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects conlei'nplated are attained as hereinafter more fully set forth, pointed out in my claim and illustrated in the accompanying drawings, in

which Figure 1 shows a front elevation of a portion of a door for installing thereon a hook embodying my invention.

Fig. 2 shows a horizontal, sectional view of the door and casin taken on the line 22 of Fig. 1 illustratmg the hook in different ositions of its movement from that shown in Fig. 1.

Fig. 3 shows a vertical, sectional view of the bar member for the hook taken on the line 33 of Fig. 1.

Fig. 4: shows a front elevation of a bar equipped with a modified form of my hook, and

Fig. 5 shows a horizontal, sectional view of the same taken on the line 55 of Fig. 4 showing the hook in a different position of its movement from that shown in Fig. 1.

In the accompanying drawing I have used the reference numeral 10 to indicate a frame around the door opening in the building and have used the numeral 11 to indicate generally a swinging door. In the form of my invention shown in Figs. 1, 2 and 3 I provide on the door near the free swinging edge thereof a bearing comprising a flat plate 12 having a central, vertically arranged, outwardly extending channel shaped portion 13, which is deeper at its upper than at its lower end as illustrated in Fig. 3. The channel shaped portion 13 forms a bar having an upright rod or shaft 15, on the lower end of which is formed an angled arm 16, which is secured to a coil spring 17.

The spring 17 is secured by means of a screw or the like 18 to the door 11. At the upper end of the shaft 15 is a horizontally extending member 19 on the free end of which is a hook 20. On the door frame is a screw eye or the like 21 to serve as a keeper. It will be noted that when the hook device is not in use the spring 17 will so act on the angled arm 16 as to normally hold the member 19 and the hook member 20 in position close to the door 11 as illustrated in Fig. 1.

When the door is closed and it is desired to lock the door by means of my hook device the hook is swung around against the pressure of the spring 17 and inserted in the screw eye 21. It may be noted in this connection that on account of the fact that the channel shaped bar 13 is tapered at its upper end more than at its lower end the lower end of the shaft 15 has some vertical play for permitting the hook member 20 to be swung up and down to permit it to clear the screw eye 21 and then to be dropped down through the screw eye 21.

In Figs. 4 and 5 I have shown a modified form of my invention in which the hook is secured on the door 11 and the screw eye 21 is secured to the frame 10. I employ a flat plate 22 having at its upper and lower ends laterally extending cars 23. On the outer edges of the cars 23 are notches 24:. Received in the notches 24 is an upright shaft 25 formed on the ends of which are parallel lateral extensions 26 connected at their outer ends by connecting member 27 and in a central loop 28. On the shaft 25 is a coil spring 29, one end of which is secured in any suit able way, the other end of which is looped around one of the extensions 26 at 30 for normally holding the connecting member 27 adjacent to the door. There is provided a hook member 31 having a shank 32 extending through the loop 28. On the end of the shank 32 opposite the hook member 31 is a loop 33, which receives the spring 29 and shaft 25.

It will be seen that the spring 29 and the yoke formed by the members 25, 26 and 27 tend to hold the hook yieldingly against the door. The members 26, 25 and 27 are of resilient material so as to normally hold the shank 32 in the same horizontal plane. The resiliency of such material, however, permits the shank 32 to be swung forwardly when the hook is to be used to permit its point to clear the screw eye 21. After the hook has been inserted through the screw eye 21 the resiliency of the parts already mentioned will tend to hold it against any accidental removal from the screw eye.

In the practical use of my improved hook it will be noticed that in either form of device the hook is normally held yieldingly against the door whenever it is not in use but when the door is closed and it is desired to use the hook it is readily and easily ex tended through the screw eye. In the form of the device shown in Fig. l enough up and downplay of the shank of the hook is permitted to allow the hook to be readily inserted into or withdrawn from the screw The same advantage is found in the form of the device shown in Figs. 4 and 5 inasmuch as the loop 33 is wide enough to per mit some vertical play of the shank 32. The form of the device shown in Fig. 4 has an other advantage in that the spring loop through which the shank 32 is extended tends to hold the shank in the same horizontal position but permits it to be sprung the screw eye and tends to yieldingly hold it in the screw eye after said hook has been once inserted into the screw eye.

Some changes may be made in the construction and arrangement of the various parts of my improved hook and it is my intention to cover by my present application any modified forms of structure or mechanical equivalents, which'may be reasonably included within the scope of my invention.

I claim as my invention:

In a device of the class described, the combination of ,a support, a channel-shaped bearing mounted on said support, a hook having at one end a right-angled extension forming a shaft received in said bearing, and having an extension at one end of said right-angled extension at an angle to said right-angled extension, a spring secured to said support and to said last extension, said channel-shaped bearing being deeper at one end than at the other for permitting limited tilting movement of said first extension.
